A=(4·8-4·1):4+(8+2)²:5
A=(32-4):4+10²:5
A=28:4+100:5
A=7+20
A=27
B=6+2·(14-1)
B=6+2·13
B=32
27=3³
32=2⁵
cmmmc (27; 46) = 2⁵ × 3³ = 864
cmmdc (27; 32) = 1
____________
A=[(6⁵:6²-2³)-5²]:3
A=[(6³-2³)-5²]:3
a=[(216-8)-25]:3
A=183:3
A=61
B=(12-3)·10
B=9·10
B=90
cmmmc (61; 90) = 2 × 3² × 5 × 61 = 5490
cmmdc (61; 90) = 1
